Abstract: The present disclosure provides an image synchronizing method, a system and a piece of electronic equipment, which can invoke a preset frame synchronization parameter when receiving fluorescence image data; and white light image data corresponding to one memory chip is invoked from N memory chips based on the frame synchronization parameter, and the white light image data is fused with the fluorescence image data, so as to obtain a first fusion image. Under a case that the white light image and the fluorescence image generate difference, this method may compensate for the difference between the white light image and the fluorescence image in a manner that the white light image data after the difference is invoked through the frame synchronization parameter, thereby ensuring an imaging effect of a fluorescence imaging system.
